The most general model-independent analysis of the lepton polarization
asymmetries in the rare B decay, \Bstt, is presented. We present the
longitudinal, normal and transverse polarization asymmetries for the τ+
and τ−, and combinations of them, as functions of the Wilson coefficients
of twelve independent four-Fermi interactions, ten of them local and two
nonlocal. These procedures will tell us which type of operators contributes to
the process. And it will be very useful to pin down new physics systematically,
once we have the experimental data with high statistics and a deviation from
the Standard Model is found.Comment: 24 pages, 8 figures, LaTe
